How Locksmiths Make an Ignition Key Without the Original

Professional auto locksmiths have several methods for creating a new ignition key when the original is missing:

• Using the VIN and key code
  Every vehicle has a unique Vehicle Identification Number (VIN). With this number, and sometimes a manufacturer-issued key code, a locksmith can cut a new key that matches your ignition precisely. This avoids the need to dismantle the lock.
• Decoding the ignition lock cylinder
  If the key code isn’t available, locksmiths can remove the ignition lock cylinder and “read” the internal wafers or pins. From this, they determine the correct key cuts and create a new key.
• Programming transponder or smart keys
  Modern cars use keys with transponders or smart fobs that need to be electronically paired to the car’s immobiliser system. Locksmiths use specialised diagnostic equipment to program the new key so it communicates correctly with your vehicle.
• EEPROM and advanced methods
  In some cases, especially with luxury or high-security models, locksmiths may access the car’s ECU or EEPROM chip to extract the necessary data. This allows them to program a fully functional replacement key.

While dealerships can also provide new keys, they usually require you to tow the car in, which is time-consuming and expensive. Mobile auto locksmiths can do the same job on site, often much faster and at a lower cost.

Is It Possible to Replace the Ignition Switch

In some cases, making a new ignition key is not enough. If the ignition lock itself is damaged or worn out, the best solution may be to replace the entire ignition switch.

How the process works:

• Disconnecting the battery: Safety comes first; your locksmith will always disconnect the battery before starting work.
• Accessing the ignition unit: The steering column trim is removed to expose the ignition switch.
• Removing the old switch: By turning the lock to the accessory position, the release pin can be pressed, allowing the ignition cylinder to slide out.
• Installing the new unit: The replacement switch is fitted into position and secured until it clicks in place.
• Testing the system: Once reconnected, the battery is tested to make sure the new switch and key work smoothly.

A new ignition switch always comes with a new set of keys. While this may mean carrying one key for the ignition and another for the doors, many drivers find this a small trade-off compared to the cost of replacing all the locks in the car.

For those who prefer a single key system, it is possible to have the door locks rekeyed to match the new ignition, but this option is usually more expensive.

Do You Need a New Key When Replacing the Ignition Switch?

Yes. Whenever the ignition switch is replaced, it comes with its own new set of keys. This is because the new ignition cylinder h

as a different internal configuration than the old one.

For most drivers, this simply means carrying two keys:

• One for the ignition,
• And one for the doors and boot.

While it may feel slightly inconvenient, it’s usually the most cost-effective and secure solution. Rekeying or replacing all the locks in the car to match the new ignition can be done, but it’s significantly more expensive.

In practice, most motorists choose to keep the original door locks as they are and use the new ignition key separately.

How Do I Find My Ignition Code?

The obvious thing to do when you lose your car key is to fetch the spare and use that one instead. However, what if you do not have a spare key? Well, the good thing is that there is another solution you can try.

You will need to get a replacement key made by a professional locksmith unless you want to remove the entire unit. To replace a car key, you will need an ignition code. This is what the locksmith will use to make a new copy of your original key.

The ignition code can be found in several places, such as:

• In the documentation that comes with the car
• Engraved as a code on the key
• On a metal plate attached somewhere on the car, for example, in the glove compartment
• Scratched or engraved on the lock
